Attestations
Transcribed from the Devanagari OCR of the printed edition at shloka_source_url (Achyuta Nand Jha ed., vol. 1) and checked word-for-word against two further independent scans of two different printed editions of the same commentary — Krishna Chandra Dvivedi's (https://archive.org/download/brihatsamhitawithbhattotpalavivrittipartidr.krishnachandradvivedi/Brihat%20Samhita%20%20with%20Bhattotpala%20Vivritti%20Part%20I%20-%20Dr.%20Krishna%20Chandra%20Dvivedi_djvu.txt) and A.V. Tripathi's (https://archive.org/download/JiUm_brihat-samhita-part-1-of-varaha-mihira-by-avadh-bihari-tripathi-saraswati-bhavan-granthamala/Brihat%20Samhita%20Part%201%20of%20Varaha%20Mihira%20by%20Avadh%20Bihari%20Tripathi%20-%20Saraswati%20Bhavan%20Granthamala_djvu.txt). Only glyph-level OCR artifacts that all three scans show to be artifacts (e.g. OCR रद्वव for रद्गव, श्व for श्च) have been normalised; every substantive reading is as scanned, and the two places where the scans genuinely differ are flagged in identification_notes.
FIVE INDEPENDENT SCHEMES, four of them pre-Varāhamihira, are set side by side by Utpala in ch. 9 — this is the single densest surviving witness to the vīthī system, and the database's vīthī entries hitherto rest on the Purāṇas alone. (a) DEVALA and others: nine triads straight from Aśvinī, Nāgā to Dahanā. (b) KĀŚYAPA: the same triads, given asterism by asterism. (c) VARĀHAMIHIRA'S OWN (BS 9.2–3), which starts the Nāgā with Svātī instead of Aśvinī and gives the Go-vīthī four asterisms and the Dahanā two. (d) PARĀŚARA, differing again (Airāvatī four, Vṛṣabhā two, Mṛga-vīthī two, Ājī = Anurādhā/Viśākhā/Jyeṣṭhā, Vaiśvānarī = Mūla + the two Āṣāḍhās). (e) GARGA, close to Varāhamihira. Plus (f) the SAMĀSA-SAṂHITĀ, Varāhamihira's own lost epitome, agreeing with (c). Utpala explicitly notes the clash — 'atra varāhamihireṇa saha bhedaḥ', 'here there is a difference with Varāhamihira' — and Varāhamihira himself refuses to adjudicate at 9.7. THREE NAME-FORMS for this road are now attested where the database had one: Vṛṣabhā (Varāhamihira BS 9.1 and Utpala's prose), Vārṣabhī/Vārṣabhā (Garga, in the compound 'gajairāvatavārṣabhāḥ' — Krishna Chandra Dvivedi's editor notes the form 'vārṣabhā' as an ārṣa usage), and Ārṣabhī (Garga again, 'ārṣabhī tu caturthī syāt'), which is the form the database has from Matsya 124.56. Content confirmed as Maghā + the two Phalgunīs by Devala, Kāśyapa, Varāhamihira, Garga and the Samāsa-saṃhitā, exactly matching the Matsya reading; PARĀŚARA alone reduces it to the two Phalgunīs.
